在中学数学教学中适当地結合学生已經熟悉了的物理知識,不但可以使学生对数学知識有更加清楚的理解,而且对于培养学生灵活运用数学知識解决实际問題的能力和提高学生学习数学的积极性也很有帮助。本文試图对怎样結合物理知識来加强代数基础知識的教学提供一些資料和方法。一、关于数和量的概念 1.量和数,常量和变量。描述一个物理过程总是归結于說明一些物理量的变化和物理量間的相互关系。即使是低年級学生,对于簡单的物理量也都比較熟悉,譬如說,时間2秒钟、貭量3公斤、路程10米、溫度—15度、电压220伏特等等,这些量都十分具体,它們都可以用某个标准(单位)来量度或比較其大小。
The proper combination of physical knowledge that students have become familiar with in middle school mathematics teaching not only enables students to have a clearer understanding of mathematics knowledge, but also helps students develop the ability to use mathematics knowledge flexibly to solve practical problems and improve their enthusiasm for learning mathematics. Very helpful. This article attempts to provide some materials and methods on how to combine physics knowledge to strengthen the teaching of algebraic basic knowledge. First, the concept of numbers and quantity 1. Quantity and number, constants and variables. Describe a physical process is always attributed to the changes in some physical quantities and the interrelationships between physical quantities. Even younger students are familiar with simple physical quantities, such as 2 seconds in time, 3 kilograms in weight, 10 meters in distance, 15 degrees in temperature, 220 volts in voltage, etc. These quantities are very specific. They can all use a standard (unit) to measure or compare their size.
